Best practice
Moving from commissioning to handover is critical as we bring next-gen energy assets into operational reality. Achieving this demands a proven strategy that integrates effective problem-solving with the reliable deployment of innovative operational solutions. This ensures projects are fully optimised from the outset. Our customers rely on our expertise to transition their projects into operation, fully prepared for the challenges of the evolving energy landscape.
Technology + Innovation
We have developed our own custom-designed online solution to enhance safety and efficiency during commissioning and start-up. Our Completion Hand Over Management System (CHOMS), is a web-based tool designed to capture completion and certification data for all aspects of a project.
It has been developed as a multi-purpose completion, certification and management system enabling a safe, auditable handover of projects, from design stage through to completion and handover for ongoing operations.
Key features include:
- Web-based system, accessible anywhere
- Designed for brownfield & turnaround (TAR) projects
- Optimised to be shared with customers, their contractors & vendors
- Visual presentation of the project hierarchy & status
- Localised storage of documents including certification, checklists, punch lists, video inspections & leak test results
- Supports safe, timely & transparent handover of systems
Bridging the gap between build and performance.
Our team brings your project online safely. We ensure systems perform as intended, streamline handover and keep operations on schedule.
